Adiabatic cooling

What does adiabatic mean? In data centers and other facilities, adiabatic processes have enabled free cooling methods, which use freely available natural phenomena to regulate temperature. How does adiabatic cooling work?

Indirect evaporative cooling is a method which uses the coldness of evaporation generated during the phase change for cooling (e.g., air cooling in an air conditioning system). This cooling technique utilizes a naturally available substance (air and water) rather than refrigeration gases to cool an environment.

Generally, more energy is required to cool a room using air-conditioners than is consumed to heat it with radiators. This reduced oncoming air temperature, achieved by creating a fine mist at the coolers air inlet, allows the cooler to supply water temperatures as low as 25°C in the Summer period. Only uses mains cold water when high ambients demand higher levels of cooling – conserving water. No need to register with the Health and Safety Executive. Refrion adiabatic coolers offer a highly efficient alternative to the Jaeggi HTK hybrid system and also other adiabatic cooling systems.

All dry coolers and adiabatic coolers have optional round tubes or high efficiency innovative oval tubes. Every day, huge quantities of fresh water are consumed through the use of traditional evaporative systems for the heat dissipation of industrial processes ( cooling towers).

The British Health and Safety Executive has confirmed that Transtherm’s adiabatic system provides “very effective management of Legionella risk”. The adiabatic process describes the heating or cooling of a body of air without any form of energy exchanged between this system and the surrounding environment. Temperature change within a pocket of air mainly takes place due to its compression or expansion as a result of a change in air pressure in the surrounding atmosphere.

When fine water droplets are formed by a spray humidifier or evaporation occurs off an evaporative matrix, then the heat energy required to change the water’s state from a liquid (water) to a gas (humid air) is considerable. Minimal water consumption – Less than of Hybrid Cooling Tower and less than 0. As a result, the liquid to be cooled can be cooled to a lower temperature than the dry temperature of the ambient air. There is no recirculation of the evaporation water.

They only use water for adiabatic cooling of the intake air when the ambient air temperature or cooling load is high. When in adiabatic mode, these systems incorporate a two-stage process. Adiabatic coolers operate as dry coolers for most of the year.

Usually, the altitude change occurs through one of two processes. An adiabatic cooling system is different to an open or evaporative cooler in that for most of the year, it operates as a dry cooling system. Water is only used to cool the air coming into the system when it’s particularly warm outside, or when the demands on the cooling system are heavier. The depressed dry bulb allows for greater system heat rejection.

Rainwater instead of drinking water The rainwater also has the enormous advantage that almost no hardness appears. Imagine a fluid cooler running fans but with the spray pump off. If the air is cool enough, the loop temperature is low enough to keep the system going whether it is HVAC or process cooling. EC fans are fitted as standard and allows each of the fans speeds to be controlled dirtectly by a 0-10V signal. The rate of change of temperature as an air mass changes elevation.

Before the fan draws the ambient air through the finned coil, the air is pre-cooled adiabatically when traversing an humidification pad. This evaporates the water in the air, thus boosting the cooling capacity. High Return On Investment.
